T0 (LZZ whom it Wmy concern:

Be it known that I, EDWARD LITTLE Roe- ERs, a citizen of the United States, residing at Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in Spring Box-Hinges, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a box the lid of which is self-opening bv or through the operation of a piece of round spring-wire which serves as the pintle for the hinge member uniting the lid to the body of the box.

Figure 1 shows a box such as used by j ewelers, the same showing my improvements with the lid open. Fig. 2 shows a difl erent but usual shaped hinge, the box-lid being 0 en. Fig. 3 shows a section through the c osed box looking at the hinge, which is longer than shown in Fig. 1, the lid being supposed to be closed. Fig. 4 shows the hinge applied to the exterior of the box; and

Fig. 5 is yet another modification showing a different-shaped hinge and spring-pintle, the hinge being shown at the inside of the box and the box closed.

Preferably the lid (1 and bottom I) of the box will be composed of metal; but they may be composed of any other usual or suitable material, and in practice the lid and body of the box may be covered and also lined with velvet, silk, leather, or any other suitable material.

In accordance with my invention I connectsay with the lid aone half 0 of a hin e, the complemental half c being at tac ed to the body of the box. Each of these hinge-halves have usual notches and projections, the projections being curled over, as represented in Fig. 1, to leave pintlespaces, and when the projections of one part enter a space of the other part the pintleholes are put in alinement for the reception of my improved combined .pintle and boxopenlng member d. This member is shown as composed of round wire having its ends (1 d bent oppositely, the end (2 overlapping and coacting with part of the box-lid a, while the end d overlaps and coacts with part of the body I; of the box. These hingeparts may be united with the" lid and body of the box in any suitable or usual way-as, for instance, by rivets e. It will be seen viewing Fig. 1, where the box-lid is open, that when the lid is closed pressure will be put upon the ends d and d that will twist, as it were, the

wire, so that the latter-will act torsionally when the pressure employed to close the lidon the body is relaxed to open the lid mon with hinges, and they receive the wire 7L2, having its ends oppositely bent, as provided for wire d, Fig. 1.

In. the modification Fig. 3 the hinge parts are of such length that the ends d (Z cross and bear on the hinge rather than onthemateriil of the box.

In the modification Fig. 4 the hinge m m is connected with the exterior of the lid and body and receives the wire, which at its extreniity is not only bent at right angles to its length, but, as shown in said figure, the extremities are directed backwardly parallel with the part of the wire serving as the pintle for the hinge.

In the modification Fig. 5 the extremities n and of the wire are bent in the same direction and cross and coact with the hinge part "115, connected with the lid, an offset n of said wire betweenits ends crossing and coacting with the hinge part n, connected with the body, so that in Fig. 5 the wire presents oppositely-directed portions that are acted upon as the lid is closed to twist the wire about its longitudinal axis.

Prior to my invention I am not aware that a single wire having oppositely-bent portions has ever been combined directl with the hinge members connecting the 11d of a box with its body, said wire not only serving as the pintle for the hinge, but also to automatically dpen the box, due to torsional strain put into the Wire when closing thelid, that it hiaiy be fastened in closed condition to the )OL y.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a box, a bod a lid, a hinge member secured to the be y, a complemental hinge part secured. to the lid, and a wire fpintle pivotally connecting said parts, said pintle having its two ends bent pln'nllel with each other In testimony whereof I have signed my toYre-scnt ofi'set portlons to engage the inner name to this specification in the presence of we I of the lid and having intermediate of its two subscribing witnesses. I

ends a portion bent laterally in the opposite EDWARD LITTLE ROGERS. direction to engiwe the inner wall of the body I Witnesses:

of the box whereby when the lid is closed the GEO. W. GREGORY,

pin is put under torsional strain. MARGARET A. DUNN.
